Kargan Dragonrider

A 2/2 for two whose entire text box is a wager on your other creatures: control a Dragon and it flies, control none and the line reads as a blank. That gating is what the design is built around. The body is priced as a plain bear, and the evasion rides for free once the condition is met, which puts the card in a small class of tribal payoffs that ask you to bend deckbuilding toward a creature type in exchange for a benefit that costs no additional mana. The wrinkle is that the flying lives in a static ability keyed to a board state rather than in the mana value: when you reliably control a Dragon the rate is excellent, and when you do not you are paying full freight for half a card. There is also a structural tension baked in. Decks assembled to flood the board with Dragons tend to want ramp and the Dragons themselves, not a small early beater holding the fort, so the enabler this card depends on is the same strategy that has little room for it. What it demonstrates cleanly is the difference between evasion earned by a keyword you can always count on and evasion contingent on a condition you have to manufacture and maintain: the moment the Dragon leaves the battlefield, the flying goes with it. The evasion is real, but it belongs to the Dragon, and this creature is only ever borrowing it.
